In this function, each process i gathers data items from each process j if an edge (j,i) exists in the topology graph, and each process i sends the same data items to all processes j where an edge (i,j) exists. The send buffer is sent to each neighboring process and the l-th block in the receive buffer is received from the l-th neighbor

In this function, each process i receives data items from each process j if an edge (j,i) exists in the topology graph or Cartesian topology. Similarly, each process i sends data items to all processes j where an edge (i,j) exists. This call is more general than MPI_NEIGHBOR_ALLGATHER in that different data items can be sent to each neighbor. The k-th block in send buffer is sent to the k-th neighboring process and the l-th block in the receive buffer is received from the l-th neighbor

Set new values for the hints of the communicator associated with comm. The call is collective on the group of comm. The info object may be different on each process, but any info entries that an implementation requires to be the same on all processes must appear with the same value in each process' info object

-- This function sets the default Gutenberg server used to satisfy requests. Instead of taking a gutenfetch_server_t * to set the server, it takes a NULL-terminated URL such as "ftp://ibiblio.org/pub/docs/books/gutenberg/". The url should contain a protocol supported by CURL a valid hostname and a directory to the base of the gutenberg texts

An HTTP/HTTPS stress tester was designed orignally as a internet usage simulator. In short, its role was to simulate the activity of many simultaneous users hitting a HTTP server. We were debugging some java code and during that process we arrived at a point where the code could withstand an acceptable number of users hitting a single URL but it could not withstand the seemingly random activity that characterizes many users hitting many URLs on a webserver. In order to debug the problem in a lab environment, I developed a program that simply read a bunch of URLs ( we used images, scripts, static html, jsps, etc. ) into memory and hit them randomly. The result was a success. We were able to break the code in the lab, an occurance which ultimately allowed us to fix it and put it into production. As the developers code improved, siege improved until we ultimately had good java code and a pretty decent regression tool. It was helpful for us, I hope it is helpful to you. In order to feel comfortable putting code into production, you need a way to measure its performance and to determine its threshold for failure. If you break your database pool at 250 simultaneous users and you average less then one-hundred simultaneous users and the code performs favorably, you can feel good about putting it into production. At the same time, if you should monitor trends in your site's activity and prepare for the moment when your traffic starts to near your threshold for failure. As a webdeveloper or websystems administrator you have little to no control over your user group. They can visit your site anytime day or night. Your domain name could resemble a popular site, yoohoo.com? And when was the last time marketing informed you about an approaching advertising blitz? You must be prepared for anything. That is why stress and performance testing is so important. I would not recommend putting anything into production until you have a good feel for how it will perform under duress

Open_vSwitch database schema A database with this schema holds the configuration for one Open vSwitch daemon. The top-level configuration for the daemon is the Open_vSwitch table, which must have exactly one record. Records in other tables are significant only when they can be reached directly or indirectly from the Open_vSwitch table. Records that are not reachable from the Open_vSwitch table are automatically deleted from the database, except for records in a few distinguished ``root set(cq(cq tables

radare2 utility to run programs in exotic environments Apr 2, 2013 SYNOPSIS rarun2 [script.rr2] DESCRIPTION This program is used as a launcher for running programs with different environment, arguments, permissions, directories and overridden default filedescriptors. The program just accepts a single argument which is the filename of the configuration file to run the program. It is useful when you have to run a program using long arguments or pass long data to stdin or things like that usually required for exploiting crackmes :) DIRECTIVES The rr2 (rarun2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting with '#'. -tag -width Fl Ar program path to program to be executed Ar stdout select file to replace stdout file descriptor Ar stdin select file to read data from stdin Ar input set string to be passed to the program via stdin Ar chdir change directory before executing the program Ar chroot run the program in chroot. requires some previous setup Ar preload preload a library (not supported on Windows, only linux,osx,bsd) Ar setuid set process uid Ar seteuid set effective process uid Ar setgid set process group id Ar setegid set effective process group id Ar setenv set value for given environment variable Ar arg[0-3] set value for argument N passed to the program EXAMPLES Sample rarun2 script $ cat foo.rr2 #!/usr/bin/rarun2 program=./pp400 arg0=10 stdin=foo.txt chdir=/tmp #chroot=. ./foo.rr2 Connecting a program to a socket $ nc -l 9999 $ rarun2 program=/bin/ls connect=localhost:9999 Debugging a program redirecting io to another terminal ## open a new terminal and type 'tty' to get $ tty ; clear ; sleep 999999 /dev/ttyS010 ## in another terminal run r2 $ r2 -d rarun2 program=/bin/ls stdio=/dev/ttys010 SEE ALSO radare2(1) , rahash2(1) , rafind2(1) , rabin2(1) , radiff2(1) , ragg2(1) , rasm2(1) , AUTHORS pancake <pancake@nopcode.org>

Pigeonhole(aqs Sieve mailbox filter tool WARNING: This tool is still experimental. Read this manual carefully, and backup any important mail before using this tool. Also note that some of the features documented here are not actually implemented yet; this is clearly indicated where applicable

This script scans a directory full of *.svg files and checks them to see if they have proper metadata. If so, it copies them into a target directory and creates a png of it. It also creates a list of PASS and FAIL for the different criteria

Todo List "Class SDLmm::SRect " 1c Extend the class with useful utility functions in regards to rectangles like intersections. "Class SDLmm::Surface " 1c Implement a better constructor scheme, where the first argument is a dummy class which specified what to do. This would allow a construct where a surface can be loaded from an image file without first having to create an unitialized object. "Class SDLmm::VideoInfo " 1c Build a status function allowing for easier access to the flags. This can be done using a bitfield which would allow for checking for multiple features at once

Todo List "Class gu::datetime::Date " 1c Parsing date from string is not implemented yet, only possible to get current system time or maximum time. "Global gu::net::Sockaddr::get_addr () const " 1c : Figure out how this could be done in type safe way. "Class gu::RegEx::Match " 1c : find a proper name for it and move to gu_utils.hpp "Global gu::URIQueryList " 1c This should be changed to real class having get_key(), get_value() methods for iterators and to get rid of std::multimap dependency in header
